The forms of the parts can be changed Without departing from the gist of they inr enti s c a med- 'WVhat I claim is:

1. Apparatus for'laying a concreteroad or pavement on a subbed-including a "truck: 7 having a cross piece constitutinga' support, a frame pivoted at one end on the truck; to

swing transversely of the road or pavement to be laid, a concrete conveyorbelt carried loy said frame said belt doWm-vardly inclined from the pivot .end of said'frame, means for supporting the free end of saidHbelt-c'onveying frame on said cros'spiece, a hopper for receiving the concrete materials and discharging the same onto the upper portion of saidbelt, and toothed means on the truck for testing and leveling the sub-bed in ad- Vance of depositing'the concrete.

'2. Apparatus for laying a concrete road or pavement on a sub-bed including a truck having across piece constituting a support; ait'ra'm'e pivoted at one end on the truck to swing transversely of the road or pavement to be laid, a concrete conveyor belt carried by said frame means for driving thebelt, means forsupporting the free end of saidbeltconveying frame on said cross ,piece a hopper for receiving the concrete materials and" discharging the same onto the rear portion of sa'idhelt, and toothed means on thetruck for testingand leveling the sub-bed in advance of depositing the concrete.
